Vehicle With Sleeping Arrangement

ABSTRACT

A vehicle with a sleeping arrangement includes a vehicle compartment, a driver&#39;s seat mounted in the compartment, the driver&#39;s seat having a bottom cushion portion and a back portion, and a passenger&#39;s seat mounted in the compartment, the passenger&#39;s seat having a bottom cushion portion and a back portion. At least one of the driver&#39;s seat and the passenger&#39;s seat may be pivotable from a normal use position facing a front of the compartment to a sleeping position oriented approximately 90° relative to the normal use position, and the pivotable seat is adapted to recline such that the bottom cushion portion and the back portion of the pivotable seat defines at least part of a generally horizontal surface together with the bottom cushion portion of the other one of the driver&#39;s seat and the passenger&#39;s seat.

The present invention relates generally to trucks and, moreparticularly, to trucks with driver sleeping arrangements and relatedfeatures.

Trucks are typically divided into the following categories: heavy dutytrucks (above 33,000 lbs (14,968 kg) Gross Vehicle Weight GVW); mediumduty trucks (19,500 lbs (8845 kg) to 33,000 lbs (14,968 kg)); or lightduty trucks (10,000 lbs (4536 kg) to 19,500 lbs (8845 kg)). Heavy dutytrucks are typically divided into the following categories: long haulhighway-type trucks with sleeper cabs; distribution highway-type truckswithout sleepers; and vocational trucks, which are specialized truckswith bodies mounted on the vehicle frames, such as concrete mixers, dumpbodies, block trucks, refuse collection bodies, etc. Medium duty trucksare often distribution vehicles for metropolitan goods transport. Lightduty trucks are often distribution vehicles for local and city goodsdelivery.

Various regulations limit the amount of time that a driver can operate atruck over the course of a day. When the driver has exceeded that limitand is not somewhere near the driver's base of operations, unless thetruck is provided with a sleeper cab, the driver may have to rent a roomor obtain some other kind of short-term lodging. The driver may, in someinstances, try to sleep in the truck cab but this is typicallyuncomfortable.

It also often happens that a driver will simply become tired and want totake a short nap. The driver may try to sleep in the truck cab but, asnoted, this is typically uncomfortable. Likewise, the driver may berequired to wait for an extended period of time during, for example, adelivery or a pick-up, and sitting in the driver's seat or waitingoutside of the cab may become tiresome or uncomfortable. Again, thedriver may try to sleep or lie down in the truck cab.

It is desirable to provide an arrangement for truck cabs that willfacilitate allowing drivers to sleep or rest in a substantially inclinedposition. It is also desirable to provide such an arrangement in trucksthat are not provided with sleeper cabs.

In accordance with an aspect of the present invention, a vehicle with asleeping arrangement includes a vehicle compartment, a driver's seatmounted in the compartment, the driver's seat having a bottom cushionportion and a back portion, and a passenger's seat mounted in thecompartment, the passenger's seat having a bottom cushion portion and aback portion. At least one of the driver's seat and the passenger's seatis pivotable from a normal use position facing a front of thecompartment to a sleeping position oriented approximately 90° relativeto the normal use position, and the pivotable seat is adapted to reclinesuch that the bottom cushion portion and the back portion of thepivotable seat defines at least part of a generally horizontal surfacetogether with the bottom cushion portion of the other one of thedriver's seat and the passenger's seat.

In accordance with another aspect of the present invention, a vehiclewith a sleeping arrangement includes a vehicle compartment, a driver'sseat mounted in the compartment, a passenger's seat mounted in thecompartment, and a cushion arrangement mounted in the vehiclecompartment. The cushion arrangement is =foldable and adapted tocooperate with the driver's seat and the passenger's seat to define agenerally horizontal surface.

In accordance with still another aspect of the present invention, avehicle with a foldable lever arrangement includes a vehicle compartmentand a lever mounted to the vehicle compartment. The lever includes ajoint arrangement having a locked mode in which the lever is movable toat least one use position and the joint arrangement having an unlockedmode in which the lever is movable between at least one use position anda folded position.

DETAILED DESCRIPTION

A portion of an interior of a compartment of a vehicle is shown inFIG. 1. In the embodiment of FIG. 1, the compartment is a cab 21 and thevehicle is a truck with a driver sleeping arrangement 23 according to anembodiment of the present invention. The portion of the truck outside ofthe cab 21 is not shown. In a typical embodiment, the cab 21 is a daycab of a truck.

A driver's seat 25 is mounted in the cab 21. The driver's seat 25 has abottom cushion portion 27 and a back portion 29. In the illustratedembodiment, the driver's seat 25 is shown on the left-hand side of thecab 21, however, the driver's seat can be disposed on the right-handside of the cab.

A passenger's seat 31 is also mounted in the cab 21 The passenger's seat31 has a bottom cushion portion 33 and a back portion 35. Thepassenger's seat 31 is shown on the right-hand side of the cab 21 in theillustrated embodiment, however, it will be appreciated that thepassenger's seat can be disposed on the left-hand side of the cab.

At least one of the driver's seat 25 and the passenger's seat 31 ispivotable from a normal use position facing a front of the cab as seenin FIG. 1 to a sleeping position oriented approximately 90° relative tothe normal use position, such as in the embodiment shown in FIG. 2. Thepivotable seat (here, the passenger's seat 31) is adapted to reclinesuch that the bottom cushion portion 33 and the back portion 35 of thepivotable seat defines at least part of a generally horizontal surface37 together with the bottom cushion portion 27 of the other one of thedriver's seat 25 (as in the embodiment illustrated in FIG. 2) and thepassenger's seat. In other embodiments (not shown), both the driver'sseat 25 and the passenger's seat 31 can pivot and recline, however, forpurposes of discussion, an embodiment wherein only one of the seats ispivoted and reclined is discussed.

For purposes of discussion, the pivotable seat will be the passenger'sseat 31, and the other seat will be the driver's seat 25. Also, whilethe terms “driver's seat” and “passenger's seat” properly describeembodiments of the invention, it will be understood that the presentinvention has application in connection with other vehicle seats, suchas rear seats. For purposes of discussion, however, the terms “driver'sseat” and “passenger's seat” will be used. Also, while the presentinvention is described here in connection with an embodiment for use ina truck cab, it will be appreciated that the present invention hasapplication in other vehicles, such as passenger cars, buses, boats,aircraft, and the like.

In the embodiment shown in FIG. 3, when the passenger's seat 31 ispivoted to the sleeping position, the bottom cushion portion and theback portion of the passenger's seat and the bottom cushion portion ofthe driver's seat define a gap 39 in the generally horizontal surface.In the embodiment of FIG. 3, a cushion arrangement 41 mounted in thetruck cab 21 and is unfoldable to substantially bridge the gap. The word“fold” is used herein with respect to movement of the cushionarrangement to describe the movement that permits the cushionarrangement to be moved from a stored position to a use position anddoes not necessarily require that the cushion arrangement be folded inthe sense of being bent or doubled up upon itself. The cushionarrangement may, for example, be slid or otherwise moved from a storedposition to a use position. The cushion arrangement 41 can be mounted inthe truck cab 21 in any suitable manner, such as by being hingedlyconnected to a rear wall 43 of the truck cab so that the cushionarrangement can be stowed in a position up against the rear wall andunfolded to the position bridging the gap between the driver's seat 25and the passenger's seat. The cushion arrangement 41 may be mountedelsewhere, of course, such as in back of the driver's seat 25 or thepassenger's seat 31 or on the floor between the driver's seat and thepassenger's seat to list but several options.

FIG. 4 shows an embodiment similar to that of FIG. 3 except that,instead of bridging a gap between the driver's seat 25 and thepassenger's seat 31, the cushion arrangement 141 folds down over theback portion 35 of the passenger's seat and then folds out over thegenerally horizontal surface at least partially defined by thepassenger's seat and the driver's seat to define a substantiallycontinuous surface over the generally horizontal surface. Substantiallycontinuous in the sense used here does not necessarily mean continuousin the mathematical sense of having no breaks or irregularities but,rather, is meant to distinguish the surface defined by discrete seats 25and 31 and bottom cushion portions thereof. While not illustrated, itwill be appreciated that the cushion arrangement 41 shown in FIG. 3 thatbridges the gap 39 can also fold out over the driver's seat 25 and thepassenger's seat 31 to form a continuous or substantially continuoussurface over the seat and back portions of those seats.

FIG. 5A shows a lever 45 disposed in the cab 21. The lever 45 in FIG. 5Ais the stick shift, however, the lever can be any member ordinarilydisposed in a cab, such as a stick shift, a brake, and the like. Thelever 45 includes a joint arrangement 47 and a lock arrangement 49. Thejoint arrangement 47 can include a universal type joint that, when in anunlocked mode in which the joint arrangement is not locked by thelocking arrangement, permits an exposed portion 45 a of the lever 45 tobe folded to one or more positions relative to a base portion 51 that isfixed to a floor 53 of the cab 21. The locking arrangement 49 can be anysuitable structure capable of fixing the exposed, “foldable” portion 45a of the lever 45 relative to a concealed portion 45 b of the leverconcealed by the base portion 51 and the floor 53 so that, when in alocked mode, the foldable portion 45 a is not foldable. The lockingarrangement 49 may, for example, include a retractable pin that extendsthrough portions of the yokes of a universal type joint 47 or, as seenin FIG. 5B, a spring loaded pin 49 a mounted on the exposed portion 45 aof the lever 45 that is received in an opening 49 b in a cylindricaltube 49 c that is cut on a diagonal at a bottom end 49 d and, as shownin phantom, is held up above yokes of a universal-type joint 47 when thelocking arrangement is unlocked and that, when the pin is removed fromthe opening in the cylinder, permits the cylinder to fall over the yokesas seen in FIG. 5B to prevent relative movement. In the latterembodiment, when it is desired to unlock the locking arrangement, thecylinder can be lifted and the pin reinserted into the opening in thecylinder. The locking arrangement 49 may also be a member that extendsalong an axis of the exposed and concealed components of the lever 45.

When the joint arrangement 47 is in the locked mode as seen in FIG. 5A,the lever 45 can be in an operating mode in which it is adapted tochange function settings corresponding to use positions of the lever.For example, when the lever 45 is a stick shift, it can shift functionsettings such as gears depending upon the position of the stick shift.When the lever 45 is a brake, it can shift function settings such aswhether an emergency brake is on or off depending upon the position ofthe brake. When the joint arrangement 47 is in the unlocked mode as seenin FIG. 1, the lever 45 is in a disabled mode and is not adapted tochange any function settings corresponding to any use positions of thelever, e.g., it is not possible to use the lever to shift gears orrelease the emergency brake. When the joint arrangement 47 is in theunlocked mode as seen in FIGS. 1-4 and shown in phantom in FIG. 5A, tothe extent that some portion of the lever 45 would extend above an upperplace of the generally horizontal surface formed by the driver's seat 25and the passenger's seat 31 and, if provided, the cushion arrangement41, the exposed portion 45 a of the lever can be folded to a storedposition so that it does not interfere with the comfort of the user ofthe sleeping arrangement 23.

In FIGS. 2-4, the pivotable seat 31 is pivotable such that the backportion 35 is closer to the other seat 25 than the bottom cushionportion 33. However, as seen in FIGS. 6A and 6B, the pivotable seat 131may be pivotable such that the back portion 135 is closer to the otherseat 25 than the bottom cushion portion 133. The embodiment of FIG. 6Ashows the back portion 135 reclined to form a substantial plane with thebottom cushion portion 133 although, as shown in phantom, it may bedesirable to recline the back portion 135 to a lesser degree. FIG. 6B,shows the back portion 135 reclined to an approximate mid-point betweenlevel with the bottom cushion portion 133 and a vertical to the bottomcushion portion. By only partially reclining the back portion 135, auser can rest in a partially inclined fashion which is, in manycircumstances, desirable.

The passenger's seat 131 can be pivoted 90° and will slide toward thedriver's seat 25 either so that the bottom cushion portion 133 of thepivoted passenger seat substantially abuts the bottom cushion portion 27of the driver's seat, as seen in FIG. 6A, or so that there is a gapbetween the bottom cushion portion of the driver's seat and thepassenger's seat, as seen in FIG. 6B. A user's legs can be placed on thedriver's seat and the user can recline the passenger's seat to a desiredangle. The embodiment of FIG. 6B may be more appropriate when it is notpractical to provide a collapsible stick shift lever 45, or it is notpossible to move the bottom cushion portions of the driver's andpassenger's seat together. In the embodiment of FIG. 6B, a user canrecline in the passenger's seat 131, the user's feet can rest on thebottom cushion portion 27 of the driver's seat 25, and the stick shiftlever 45 can extend between or on opposite sides of the user's legs. Inall embodiments of the present invention, the driver's and passenger'sseats can be provided with arm rests 10, as seen in FIG. 6B. The armrests 10 can be adjustable in a conventional manner, and can be moved toa position so that they do not interfere with a user's ability torecline or lie down on the seats.

It may be desirable in any of the embodiments described herein that atleast one of the pivotable seat and the other seat is slidable towardand away from the other one of the pivotable seat and the other seat.This can be accomplished in any suitable manner, such as by mounting aslidable one of the seats on a track 55 on the floor 53 of the cab 21 asseen in FIG. 1. Alternatively, a slidable seat may be slidably mountedon a track 57 on a structure such as a post 59 that is fixed to thefloor. The slidable seat will ordinarily be adapted to be locked in adesired position relative to the other seat by any suitable means, suchby as a clamping arrangement (not shown) fixed to a sliding member andadapted to contact a non-sliding component of the cab.

The sleeping arrangement according to another embodiment of the presentinvention shown in FIG. 7 does not require, but does not preclude, thatone or both of the driver's seat and the passenger's seat be pivotable.In this embodiment, the driver's seat 225 is mounted in a cab 221, andthe passenger's seat 231 is mounted in the cab. A cushion arrangement241 is mounted in the cab and is unfoldable and adapted to cooperatewith the driver's seat and the passenger's seat to define a generallyhorizontal surface.

In FIG. 7, a gap 239 is defined between the driver's seat 225 and thepassenger's seat 231 and the cushion arrangement 241 bridges the gapwhen in an unfolded position. The cushion arrangement 241 can beunfoldable over bottom cushion portions 227 and 233 of the driver's seat225 and the passenger's seat 231, respectively, to define asubstantially continuous surface over the bottom cushion portions andthe gap 239. Of course, in other embodiments (not shown) the cushionarrangement may merely bridge the gap between the driver's seat and thepassenger's seat and may not unfold over the bottom cushion portions.

FIGS. 8A-8C show embodiments of a cushion arrangement 341 such as isusable by itself or in connection with seating units such as thedriver's seat and passenger's seat shown in FIGS. 1-4 and 6-7. As seenin FIG. 8A, the cushion arrangement 341 can include a central panel 341a that is hingedly mounted to, e.g., the rear wall 43 of the cab 21. Thecentral panel 341 a is shown as being hingedly mounted to the rear wall43 of the cab 21 at a bottom side of the central panel, however, thecentral panel may be mounted in a variety of forms, and may have morethan one degree of freedom. For example, the central panel 341 a may besecured to a surface by a joint such as a ball and socket joint at acorner of the central panel so that the central panel can be folded downor up about a horizontal axis as well as folded about a vertical axis.The central panel 341 a can be unfolded over a portion of a driver'sseat or a passenger's seat, or both, or may be unfolded over a gapbetween the driver's seat and passenger's seat. The cushion arrangement341 can be secured in a stored position by any suitable means, such asstraps, hook and pile fasteners, and the like.

As seen in FIGS. 8B-8C, left and right panels 341 b and 341 c,respectively, can be hingedly mounted to the central panel 341 a. Theleft and right panels 341 b and 341 c can be unfolded relative to thecentral panel 341 a so that they extend over seat and/or back portionsof driver's seats and passenger's seats.

The cushion arrangement 341 can be provided with structures such asinternal support beams to facilitate supporting a user over, e.g., a gapbetween a driver's seat and a passenger's seat, or can be entirely voidof such support structures. In addition, the cushion arrangement 341 canbe provided with structures such as support beams to facilitate usingthe cushion arrangement with or without the driver's seat and thepassenger's seat. For example, internal support beams can be provided,along with unfoldable legs for supporting the cushion arrangementwithout the driver's seat and the passenger's seat. Also, supportmembers and/or legs can be secured to the cushion arrangement in anysuitable fashion after unfolding, instead of having such members formingpart of the cushion arrangement.

In all of the embodiments, the reclining seats may be reclined to adesired angle in a substantially conventional manner, such as by a lever61. The lever 61, a separate lever, or some other conventional structuremay also be arranged to permit or prevent pivoting of the seats relativeto one another. Of course, conventional electronic seat positioncontrols (not shown) may be provided instead of levers and the like.

References to a “cushion” herein are not intended to limit structuressuch as the bottom cushion portion of the seat or the cushionarrangements to structures such as padded surfaces, although it isanticipated that such structures will ordinarily be padded. The bottomcushion portion and the cushion arrangements may, for example, beunpadded, hard structures.

In the present application, the use of terms such as “including” isopen-ended and is intended to have the same meaning as terms such as“comprising” and not preclude the presence of other structure, material,or acts. Similarly, though the use of terms such as “can” or “may” isintended to be open-ended and to reflect that structure, material, oracts are not necessary, the failure to use such terms is not intended toreflect that structure, material, or acts are essential. To the extentthat structure, material, or acts are presently considered to beessential, they are identified as such.

While this invention has been illustrated and described in accordancewith a preferred embodiment, it is recognized that variations andchanges may be made therein without departing from the invention as setforth in the claims.
